x(5x + -3) = (5x + 8)(x + -3)

Reorder the terms:
x(-3 + 5x) = (5x + 8)(x + -3)
(-3 * x + 5x * x) = (5x + 8)(x + -3)
(-3x + 5x2) = (5x + 8)(x + -3)

Reorder the terms:
-3x + 5x2 = (8 + 5x)(x + -3)

Reorder the terms:
-3x + 5x2 = (8 + 5x)(-3 + x)

Multiply (8 + 5x) * (-3 + x)
-3x + 5x2 = (8(-3 + x) + 5x * (-3 + x))
-3x + 5x2 = ((-3 * 8 + x * 8) + 5x * (-3 + x))
-3x + 5x2 = ((-24 + 8x) + 5x * (-3 + x))
-3x + 5x2 = (-24 + 8x + (-3 * 5x + x * 5x))
-3x + 5x2 = (-24 + 8x + (-15x + 5x2))

Combine like terms: 8x + -15x = -7x
-3x + 5x2 = (-24 + -7x + 5x2)
